About Allied Waterproofing & Drainage in Seattle, WA

Given our local climate, a moisture control inspection is a detailed assessment of your property's vulnerabilities. Our technicians examine crawl spaces, basements, and foundation perimeters for signs of water intrusion, condensation, and poor ventilation. We use tools like moisture meters and thermal imaging to identify hidden problems, then provide a clear report and recommendations, which may include vapor barrier installation, sump pump systems, or improved drainage—all tailored to Seattle's specific conditions to protect your home's structure and indoor air quality.

Absolutely. These are common issues in Seattle homes, often related to grease buildup or partial clogs in the pipes. We start with a video pipe inspection to locate the exact cause of the blockage without guesswork. For persistent jams, we can repair or replace the garbage disposal unit and clear the line. If the problem is deeper, such as a compromised pipe joint, we offer precise repair or trenchless replacement to fix the leak and restore proper flow, preventing further water damage to your cabinetry or floors.

Trenchless repair is a method we often recommend because it minimizes disruption to your Seattle property. Instead of digging large trenches, we create small access points to insert a new, durable pipe liner within the old one. This is a cost-effective solution that preserves your landscaping, driveway, and hardscaping. It's a reliable, long-lasting repair ideal for addressing cracks, root intrusion, or corrosion in sewer and water lines, completed efficiently with the quality workmanship we've delivered since 1990.
